Chainsaw Bar Length Vs CC

The length and cubic centimeter of a chainsaw bar.

If you ever try to shop around for a chainsaw for the first time, you will immediately get acquainted with technical terms like chainsaw CC and chainsaw bar length. Although these terms seem self-explanatory, you might also get a tad confused about their implications and relevance to your choice of chainsaw model. Hence, it will help if you have a good idea of these two terms.

The bar length, of course, refers to the length of the chainsaw bar, which is the narrow object around which you wrap the chain. The CC, on the other hand, refers to cubic centimeters and indicates the volume of the chainsaw engine. Before selecting a chainsaw model and brand, it will be best to have a working idea of these two technical terms.

Understanding the Chainsaw Bar Further

As mentioned above, the bar length refers to how long the bar is. The bar, of course, is the thing around which the chain gets wrapped. You can’t simply measure the length of the bar by measuring the visible bar. The reason is that the more significant part of the bar lies hidden inside the chainsaw. Thus, you only see the cutting length of the bar. 

The Ideal Bar Length

The ideal bar length for your use hinges on the job you will perform with your chainsaw. For example, if the bar length is too long, you may find it hard to control. Nevertheless, you might fail to cut through the wood if it is too short. 

The ideal range of bar length is from 8 to 16 inches if you will only engage in light pruning and trimming. But if you intend to fell a small tree or cut large limbs, you might as well go for bars within the length range of 16 to 18 inches. However, if you want to cut trees in medium sizes, you better go for the 18 to 20-inch bar length

Yet, if you are desirous of felling an enormous tree, go for the 20 to 24-inch bar length range. You may easily understand what bar length is and its implications. Nevertheless, you might get a tad confused about the implications of the CC.

What IS CC in Chainsaw Bar?

The acronym CC means cubic centimeters. And when you speak of cubic centimeters, it refers to the volume of the chainsaw engine or its carrying capacity. Thus, the greater the CC, the more powerful the engine is, and the more efficient and easier your cutting job will be. If you want to determine the engine’s CC, you can use the formula given below:

.07854 multiplied by Bore2 multiplied by Stroke multiplied by the number of cylinders. 

The number 0.7854 is constant, while the Bore2 refers to one cylinder’s width or one of the cylinder’s circle’s diameters. So, you need to square it. On the other hand, the stroke is the cylinder’s length from one end to the other, and the number of cylinders refers to how many cylinders the engine has.

What is the Appropriate CC for Your Chainsaw?

The CC you will need depends on the type of job you will perform with your chainsaw. You will only need something lower in CC if you engage in lighter cutting tasks. Nevertheless, if you will engage in more challenging cutting tasks, you might as well go for something with higher CCs. 

As mentioned above, a small job includes trimming, pruning, and felling a small tree. With these tasks, you only need something below 30cc. Moderate tasks, however, involve felling an average tree or cutting medium-sized logs. You can use something with 40cc for these tasks. Difficult tasks, however, include felling down a huge tree. Besides, you might need something with 50cc for these tasks.

Which Should You Prioritize: the CC or the Bar length?

When selecting a chainsaw, you should not question whether CC is more important than the bar length or vice versa. The reason is that both metrics are essential if you want to zero in on the ideal chainsaw for your use. 

Bar length is important because it tells you how you can easily control the chainsaw. Besides, it indicates how thick the wood you can cut with your chainsaw. 

Of course, you want to know beforehand if the chainsaw can handle a task, and bar length can answer your apprehension about the chainsaw’s capability. 

On the other hand, CC is a critical metric because it tells you the chainsaw’s power. If the chainsaw packs too much power, you might risk injuring yourself when using it. So, CC will tell you how much power a chainsaw packs. 

Remember that if your chainsaw doesn’t have enough power, you might fail to cut the material you intend to cut. If it is very powerful, you also risk injuring yourself. Hence, understanding the CC enables you to strike a balance between the chainsaw power and the task you would like to perform.

On Picking the Chainsaw’s Blade Length

As a beginner, you might be confused about selecting the blade length for your chainsaw. Two factors, however, come to the fore when selecting a chainsaw blade length: your work and your working area. Chainsaws get categorized according to your job type or capacity: Light-duty, medium-duty, and professional chainsaws. Below is a short description of each of these categories:

Light-duty Chainsaws

If you will often engage in tasks like trimming and pruning, the light-duty chainsaw is best for you. Besides, if you’re a tyro in using a chainsaw and want to get the hang of its use, you might as well go for the light-duty chainsaw. 

Light-duty chainsaws feature blade sizes that range between 10″ to 14.” They also feature a 30 to 45cc engine displacement. You can use this type of saw for your yard work, and they pack more power than their corded counterparts. You can also use them to cut smaller trees and larger limbs. Nevertheless, this type of chainsaw will not suffice for felling larger trees, cutting large wood, and storm damage cleanup.

Medium-duty-to Heavy-duty Chainsaws

You will have no qualms using the light-duty chainsaws for tasks you consider suited for such a chainsaw. But as you move to the medium to heavy-duty ones, things become a bit complicated. Besides, if you’re a beginner, you should not operate this type of chainsaw, for its use is fraught with danger. 

The blade size range for the medium to heavy-duty chainsaws is from 14″ to 18.” Their engine displacement likewise ranges from 40cc to 50cc. Using heavy-duty ones for your yard work can be overkill, and it can be a liability when doing a minor job. But still, you can use it to cut larger branches and medium-trunk trees.

Professional Chainsaws

Professional chainsaws are perfect for those whose job is cutting or felling giant trees. If your source of income is cutting trees, you might as well go for the professional chainsaws. The range of size of professional chainsaws is from 60cc to 120cc. You can use this type of chainsaw for consistent heavy-duty work.

Professional chainsaws get equipped with more powerful engines. They also feature a longer bar chain with anti-kickback chains. Moreover, they work a lot easier, and they are more expensive than the previously discussed types of chainsaws.

The professional units, of course, carry an edge over the light-duty and medium-duty chainsaws. They have more fuel capacity, and they are heavier. Besides, they pack more power and allow for easy access to their inner compartments. Moreover, you got plenty of brand and model options to choose from.

Electric Chainsaws

Another type of chainsaw is the electric chainsaw. Since it is electric, it comes with a cord or may be powered by a powerful battery. As a beginner, it will be best to use an electric chainsaw to get the hang of its use. 

Electric chainsaws also come with a smaller range of blade sizes from 8″ to 12.” They are also perfect for light-duty works like cutting small limbs, pruning, and trimming. 

You can also use them for removing larger limbs or felling small trees. The use of electric chainsaw assures you continuous power as long as you can connect it to a power outlet, or its battery has not yet run out.


As you read through this post, you will quickly discover several essential factors to consider when buying a chainsaw. First, you need to consider the work you would like to do more often and the qualities of the chainsaw you will buy. Other factors to consider are the engine displacement measured in CC and the blade length. The saw’s horsepower determines the length of your blade. Likewise, it will be good to note your level of expertise as a user of a chainsaw and the safety tips you need to employ when using such a powerful tool.

As to the question of importance between the CC and the bar length, it is apparent that both metrics are essential. They both factor well in determining the suitable chainsaw for your works. As such, it is not warranted to set aside one factor in favor of the other when choosing a chainsaw for your use. And if you want to zero in on the ideal chainsaw for your use, it will be best to consider both factors in your choice of a chainsaw.
